MEDICINAL VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 611,560, dated September 27, 1898.

' Application filed March 1, 1898.

T0 at whom it may concern:

Be it known that I, ARTHUR MARSHALL CHAMBERS, a subject of the Queen of Great Britain, residing at Thorncliffe, in the county of York, England, have invented certain new and useful Improvements in Medicinal Vaporizers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in Vaporizers in which medicated liquids or other compounds are vaporized for service in cases of asthma or like diseases or for disinfecting purposes; and the objects of my improvements are, first, to provide means by which the vaporization is continued regularly and uniformly for long periods without attention, and, second, to afford facilities for regulating and adjusting the speed of vaporization, so that it is more or less rapid, as may be desired, while portable. I attain these objects by the devices illustrated in the accompanying drawings, in which- Figure 1 is a side view, and Fig. 2 a front View, of the Vaporizer. Fig. 3 is vertical section through the evaporating-dish, and Figs. 4 and 5 are a plan and side view, respectively,

Similar letters refer to similar parts through out the several views.

a is the base, stamped up out of tin-plate or other suitable material and having at its recessed center a circular opening to receive a Figs. 4 and 5,) having at one side a ring or handle 0, by which it can be readily lifted in or out of the opening in the base a, in which it fits.

The holder 12 receives the lower end of a candle d, of the kind well known and largely, used as pyramid night lights, which when once lighted are capable of giving, without attention, a steady flame for many hours.

From the base a rises a vertical cylinder 0, which surrounds the candle d, except on one side, at f, which is open for a sufficient height to allow the introduction and removal of the holder 1) and candle d, and upon the cylinder Serial No. 672170. (No model.)

6 is attached a handle g, by which the entire vaporizer can be carried about.

Around the upper part of the cylinder c are a series of openings in the form of vertical slits i i i above the opening f at its side.

It is a cylindrical case fitting freely around medicinal or disinfecting material to be heated or vaporized. It is made in the shape of a hollow bowl, as shown in section in Fig. 3, a flange or rim m around its upper edge fitting upon and being supported by the upper edge of the cylinder 6.

The bowl Z, of copper or other metal or ma terial, is of such thickness, especially at the bottom, that the heat from the burning candle d is only transmitted through it sufficiently readily to keep the contents at just the required temperature to insure their slow and uniform vaporization. I

The substance to be vaporized is placed in the bowl l, and the holder 1), having the lighted candle d fitted into it, is placed in the recess in the base a. The bowl is thus heated and kept hot, and the intensity of the heat can be regulated and varied by adjustment of the perforated outer case h, by means of which more or less of the heated air is allowed to pass out through the perforations i.

The vaporizer is very simple, cheap, portable, and easily used and is very effective for the purposes required. I

What I claim as my invention, and desire to secure by Letters Patent, is

A vaporizer consisting of a base having a circular opening in its center for the reception of a lamp or candle holder, of a hollow cylindrical body portion, provided with a handle, open at its upper end to receive an evaporating-pan, and provided at its lower end with a vertical opening for the introduction of a lamp or candle ran annular rib around the upper portion of said cylinder above said vertical opening; a series of vertical slots cut in In testimony whereof I have hereunto afsaid cylinder above said annular rib, and a fixed my signature in presence of two Wit- :0 movable circular band,surrounding the upper nesses. portion of the said cylinder, resting on said annular rib and provided with a series of vertical slots, adapted to register with the slots WVitnesses: in the upper portion of the said cylinder, sub- CHARLES EDWARD VYNER, stantially as described.
